SPLIT PULLE'YQ Specification of Letters Patent.

. Patented Feb. 5,1907.

Application filed June 30,1906. Serial No 324,122.

Paso, in the county of El Paso and Stateof Texas, have invented certain new and useful Improvements in Split Pulleys, of which the following is a specification.

tains especially to split pu eys of the c ass a" split s ider or' open-web pulley of metal having interlocking parts. The .parts -or halves of said class of pulleys invariably have i to be slid longitudinally'to effect the locking and unlocking of the parts in applying the pulleys to a shaft and in removing it thereromi,

The mainpurpose, therefore, of this invention is to furnish a pulley of such construc out sliding them longitudinally.

' -:The object of the invention is to furnish havin t e "joining faces of its rim and hub provi ed with'beveled walls, forming keyopenings) V, I

' The object, further, of the invention is to provide in a split pulle a hub the coacting aces 'ofwhich form a ongitudinal key-seat V upon opposite sides of the shaft opening or hearing and a splitulley rim the coacting faces of which form ey-seats perpendicular part of this application, Figure 1 is a side elevation of a pulley embodying my invention, Fig. 2 is a peripheral elevation of ti e pulley. ig. 3 is a perspective view of the male member of the pulley, partly broken away. Fig. 4 is a similar view of the female member of the pulley, partlvbroken away. Fig. 5 is a section on the line y 1;, Fig. 1, u ith the keys removed. Fig. 6 is a section on the line a (1:, Fig. 2, with the keys removed. Fig.

7 is a perspective view of the keys.

The same reference-numerals denote the same parts throughout the/several views of- .the drawings.

The invention is applicable to split pulleys of various character and design; but the l termed .male and female parts. This invention relates to ulleys, and erkey-seats.

pering flan spider type of pulley herein shown is prefer It has a halved hub 1, connected to a hub-face 6 of the female part has a pair of longitudinal flanges 7 flush w ith the periphery of the hub. The flan es taper in opposite directions from onesi e of the hub to the other, and the ta ering face 8 of each flange is beveled inward y throughout its length.

The female rim-face 9 is formed b a rimlug 10, havin a pair of flanges 11, t 1e inner faces 12 of Winch are beveled inwardly and ta er one in the opposite direction to the oter. .The hub-face 13 of the male part has a air of cleats 14, one side of which is flush with the shaft-bearing and the other side of which is beveled, and said beveled sides taper in opposite directlons. The male rimface 15 is formed by a lug 16 andhas a central oleat 17, the sides'of which are beveled which draws and clamps the parts tightly together. In adjusting the pulley to various positions onthe shaft the keys have only to e partly withdrawn to loosen the parts sufficiently to move the pulley withoutseparation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A split pulley having longitudinal hubflanges and cleats, rim -flanges and cleats perpendicular to the hub-flanges and cleats, and keys interposed between each set of said flanges and cleats to lock the pulley parts together.

2. A split pulley having longitudinal taes and cleats in its hub, tapering flanges and cleats in its rim per )GIKilCUlfiI' to the hub-flanges and cleats, and licys inter posed between each set of said flaiwcs and cleats to clamp the pulley parts togct. 101'.
